Twin screw extruder CTE PLUS - series with new gearboxes

With the CTE PLUS Coperion Nanjing offers a new twin screw compounding system with a very attractive cost/performance ratio. The precise manufacturing of the CTE PLUS series ensures the economical processing of a wide range of applications at high product quality.

To improve reliability and to ensure longer life time Coperion Stuttgart, Germany, has engineered new gearboxes for the CTE PLUS that can bear a specific torque of 7.2 Nm/cm³ and are exchangeable with old generation CTE’s gearboxes. It offers a new terminal box that meets highest safety standards and is supplied on a unitized base frame at lower cost.

Before delivery each CTE PLUS extrusion system is subjected to a Factory
Acceptance Test (FAT) at the Coperion Nanjing site to ensure high quality standards. As an option the CTE PLUS series can be provided with TÜV CE certification.

Twin screw extruder CTE 65 PLUS

The CTE PLUS is available in one-stage and two-stage version. The CTE PLUS two-stage compounding system is mainly designed for the modification and compounding of heat and shear sensitive materials.
